JsonTableFunction class final

Calls json table-valued functions in drift.

With JsonExtensions.jsonEach and JsonExtensions.jsonTree, a JSON value can be used a table-like structure available in queries and joins.

For an example and more details, see the drift documentation

Inheritance

Properties

$columns → List<GeneratedColumn<Object>>
All columns from this table or view.
finalinherited
aliasedName → String
The (potentially aliased) name of this table or view.
finalinherited
arguments → List<Expression<Object>>
The arguments passed to the table-valued function.
finalinherited
asDslTable → JsonTableFunction
Type system sugar. Implementations are likely to inherit from both TableInfo and Tbl and can thus just return their instance.
no setterinherited
atom → Expression<DriftAny>
The value, or null if this is not a scalar value (so either an object or an array).
no setter
attachedDatabase → DatabaseConnectionUser
The generated database instance that this view or table is attached to.
finalinherited
columnsByName → Map<String, GeneratedColumn<Object>>
Gets all $columns in this table or view, indexed by their (non-escaped) name.
latefinalinherited
entityName → String
The (unalised) name of this entity in the database.
no setterinherited
fullKey → Expression<String>
The JSON key that can be passed to functions like JsonExtensions.jsonExtract to find this value.
no setter
hashCode → int
The hash code for this object.
no setterinherited
id → Expression<int>
An id uniquely identifying this element in the original JSON tree.
no setter
key → Expression<DriftAny>
The JSON key under which this element can be found in its parent, or null if this is the root element.
no setter
parent → Expression<int>
The id of the parent of this element.
no setter
path → Expression<String>
Similar to fullKey, but relative to the root argument passed to JsonExtensions.jsonEach or JsonExtensions.jsonTree.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
type → Expression<String>
The result of calling sqlite3_type on this JSON element.
no setter
value → Expression<DriftAny>
The value for the current value.
no setter

Methods

createAlias(String alias) → ResultSetImplementation<JsonTableFunction, TypedResult>
Creates an alias of this table or view that will write the name alias when used in a query.
override
map(Map<String, dynamic> data, {String? tablePrefix}) → FutureOr<TypedResult>
Maps the given row returned by the database into the fitting data class.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
writeInto(GenerationContext context) → void
Writes this component into the context by writing to its GenerationContext.buffer or by introducing bound variables. When writing into the buffer, no whitespace around the this component should be introduced. When a component consists of multiple composed component, it's responsible for introducing whitespace between its child components.

Operators

operator ==(Object other) → bool
The equality operator.
